VEHICLE-SPRING.

SPECIFICATION forming part of Letters Patent No. 238,649, dated March 8,1881.

Application filed August 14, 1880 To all whom it may concern:

Be it known that I, HARRY S. CLARK, of Towanda, in the countyof Bradford and State of Pennsylvania, have invented a new and valuable Improvement in Vehicle-Springs; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 10f the drawings is a representation of a bottom view of thisiuvention. Fig. 2 isa rear-end view of the same. Figs. 3 and 4 are detail, perspective, and sectional Views of the coupling.

This invention has relation to improvements in Vehicle-springs; and it consists in the construction and novel arrangement of two transverse half-ellipticsprings arranged in frontand rear, and two pairs of quarter-elliptic springs connected to the ends of said half -elliptic springs by ball'coupliugs or angle-joints, and to two independent transverse bars under the body of the vehicle, all as hereinafter shown and described.

In the accompanying drawings, the letter A designates side bars, to which are secured the two transverse bars B B, arranged, respectively, under the front and rear portions of the vehicle-body.

0 represents the rear axle, and D the headblock, connected thereto by a reach, E; and F F indicate half-elliptic springs running transversely, and secured, respectively, to the axle and head-block by their middle portions in such a manner that their ends extend outward and upward, as shown in the drawings.

To the ends of the elliptic half-springs are secured angle joints or ball-couplings G, whereby the convex quarter-springs H, which are fastened obliquely in pairs respectively (Model) to the front and rear bars, B B, are connected to the ends of said elliptic half-springs. In making this connection a bah-coupling is preferred, consisting of a sectional head or cap, a, designed to receive the end of the halfspring, and having a socket, b, in which is arranged the ball 0, having a neck, d, and bracket 6, to which the end of the quartersprin is connected. This ball-couplingis arranged under the half-spring, so that the end of the quarter-spring is thereby suspended from the end of the half-spring. The nature of the joint is such that it relieves the steel from any twisting strain when loaded, and renders it unnecessary to adopt any certain angle in securing the quarter-springs to the cross-bars. The latter are bolted to the sills of the body at a suitable distance from each other to suit the length of the quarter-springs as well as the length of the body and reach. These bars are designed to be made of sufiicient width and thickness to support the ends of the quarter-springs, which are bolted thereto.

What I claim, and desire to secure by Letters Patent, is

The combination, with two pairs of oblique quarter-springs, H, bolted or clipped diagonally across two separate front and rear bars, B, of two transverse half-elliptic springs, F, arranged in front and rear, and the hall oranglejoints Gr, whereby the ends of the quartersprings are suspended from the ends of the half-springs, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

HARRY S. CLARK.
